Thanks Rusty, I'm sure there's more to it than flipping the pickup upside-down. I'm just not very technical, so that's just the first thing I noticed.

@ Rossfloss: just look up some vintage Peter Green (Fleetwood Mac) on Youtube. For me there's no push-pull pot, it's just wired that way so you get that out-of-phase sound in the middle position. On a clean amp it reminds me a lot of the T-Bone Walker sound. It's got that "honking" sound in the midrange. I think it's a great sound for blues.

T-Bone's ES-5 had the middle pickup out-of-phase with the other two, which is why you're hearing that. I can also get some great BB King sounds, even though, to my knowledge, his guitars were never wired/equipped this way.
